A delicious Paleo Mexican Casserole made with cauliflower rice, ground beef, chopped tomato, peppers, jalapeños, butternut squash and delicious Mexican spices! This one pan dish is sure to be a hit with the whole family. It’s Grain Free, Gluten Free, Dairy Free, Paleo, Whole30, SCD.

A Mexican casserole has been stuck in my head for weeks now. I saw photos in a magazine recently of a super cheesy, rice, tortilla and corn casserole that literally had me drooling onto the pages.

I knew I had to create something similar, except without cheese, rice, tortillas or corn…so really not similar at all. Welcome to the world of recipe creating on a restrictive diet.

I am really happy with how this paleo Mexican casserole turned out, even without all of the ingredients included in most Mexican casseroles. This one is packed with cubes of butternut squash (which you could swap for sweet potato if you are Paleo), ground beef, peppers, jalapenos, cauliflower rice, chopped tomatoes and lots of scallions.

Everything is cooked in a cast iron skillet which means there is only 1 dish to wash at the end. Hallelujah!

The paleo Mexican casserole is baked in the oven until the cauliflower rice is tender and the top because nice and crunchy.

If you are not on a restrictive diet feel free to add in other ingredients such as cheese or corn kernels. I served big scoops of the casserole with salsa, avocado, chopped tomato and chipotle sour cream.

Can I use frozen cauliflower rice? How would that change the cook time?
My family LOVES this recipe. I use carrots instead of squash (to make it keto) and I used chopped tomatoes instead of canned because I have yet to find canned diced tomatoes without “citric acid” for my fructose intolerant hubby. However, it is still utterly delicious and we love it!!! Thank you for sharing this recipe ❤️👍👍👍
We loved it! Used ground turkey and black beans with avocados, chopped tomatoes, sliced olives, grated cheese and plain Greek yogurt on the side. It was great caramelized in skillet with soft runny egg on top!
She does state in her recipe to omit beans if whole 30 or paleo.
I wasn’t really expecting much from this recipe but my husband and I love it. I added cilantro and salsa on top and it was so delicious! I’ll be bookmarking this one!
So happy that you enjoyed it!!
Looks yummy!! Suggestions for if I don’t have a skillet that can transfer to the oven?
You could make everything on the stove top in a pan and then pour it into a casserole dish to bake in the oven
Excellent recipe! My whole family loved it.
I’m so happy to hear you enjoyed it! 🙂
